Mobile detector using RSSI for vehicular repeater prioritization
First Claim
1. In a communication system comprising a portable radio, a plurality of mobile radios and at least one mobile radio having a vehicular repeater, a vehicular repeater prioritization system comprising:
- receiver means for receiving portable radio signals;
transmitter means for transmitting the portable radio signals received by the receiver means;
monitor means for monitoring transmitted mobile radio signals;
a delay state counter coupled to the transmitter means for delaying the transmission of the portable radio signals received when said delay state counter is greater than a desired priority state and not delaying the transmission of the portable radio signals received when said delay state counter is equal to said desired priority state; and
a received signal strength indicator for determining the strength of transmitted mobile radio signals, the received signal strength indicator being coupled to the delay state counter for decrementing the delay state counter when the monitor means does not detect a transmitted mobile radio signal having at least a predetermined received signal strength level.

Abstract
A communication system (10) comprises a portable radio (20) and a plurality of mobile repeaters (12), a mobile repeater system 200 comprising a portable signal receiver (224) for receiving portable radio signals; a mobile transmitter (218) for transmitting the portable radio signals received by the portable receiver; a mobile receiver (226) for monitoring mobile transmissions; a delay state counter (202) for delaying the transmission of the portable radio signals received; and a received signal strength indicator (204) for determining the strength of received mobile radio signals, the received signal strength indicator being coupled to the delay state counter, via a controller (206), for decrementing the delay state counter when the mobile receiver does not detect a mobile transmission having at least a predetermined received signal strength level.

2. A communication system comprising:
-
a vehicular repeater comprising; a portable signal receiver for receiving signals from portable radio units; a controller coupled to a mobile transmitter; a delay state counter coupled to the controller, for delaying the transmission of radio signals received by the portable signal receiver when said delay state counter is greater than a desired priority state and not delaying the transmission of the portable radio signals received when said delay state counter is equal to said desired priority state; a mobile radio comprising; a mobile receiver for monitoring transmissions by other mobile radios; said mobile transmitter coupled to the portable signal receiver for transmitting the signals received by the portable signal receiver; and a received signal strength indicator, coupled to the controller and to the mobile receiver, for determining the strength of the transmissions by other mobile radios, the received signal strength indicator being coupled to the controller for decrementing the delay state counter when the mobile receiver does not detect a mobile transmission having at least a predetermined received signal strength level. - View Dependent Claims (3, 4, 5)

6. In a communication system comprising a plurality of priority and non-priority repeaters, at least one portable radio, and a plurality of mobile radios, a method for prioritizing a non-priority repeater, comprising the steps of:
-
(a) receiving portable radio signals in said non-priority repeater; (b) monitoring a delay state counter of said non-priority repeater and if said delay state counter is greater than a desired priority state, delaying the transmission of portable radio signals received; (c) determining the strength of transmitted mobile radio signals; (d) decrementing said delay state counter when said mobile radio signal having at least a predetermined received signal strength level is not detected until a priority state is reached; and (e) transmitting the radio signals received in step (a) if said delay state counter is equal to a desired priority state.
